As part of CNFS configuration, a service group called cfsnfssg_dummy gets created. This service group is mostly offline.

There is a limit on the number of service groups that can be created in Cluster Server (VCS). If this limit is reached, then cfsnfssg_dummy serves as the service group in which resources get created during cfsshare unshare and cfsshare delete operations.

See the Cluster Server Administrator's Guide for information about the GroupLimit attribute.
